Hi all, i have plugged a serial cable on the server and started a tty on it. In fact my server has com0 and com1 port but it seems com1 is the real console port. I have also set ddb.console=1 to sysctl.conf but when i send break or ctrl+alt+escape in the console terminal nothing happen. I am connected on another switch (before i thought it's a cisco 2960 communication problem, but it seem not, i'm on a dell powerconnect 6224). Why break doesn't have effect on com1 ? -- Best regards,
